Sprint is committed to connecting you today and tomorrow with emerging technologies like 8T8R radios that boost our 2.5 GHz signal and Wi-Fi calling, which allows customers to make domestic and international calls over wireless Internet connections.

The next generation of call quality and clarity is available nationwide.HD Voice provides a fuller, more natural-sounding calling experience on HD Voice-enabled phones on the Sprint Network. This is accomplished two ways. First, the octave range of voice calls has been expanded. Second, noise-cancelling technology isolates just the voices on the call, virtually eliminating background noise no matter what it may be.
